Invalid Memory Access in version 5.20.0

[Under-estimate]

The latest version of tess4j (5.20.0) will always throw the following error when doing OCR. The previous version (5.19.0) works fine.

Exception in thread "main" java.lang.Error: Invalid memory access

Can you tell us more about your environment, such as OS, Java version, code snippet, etc.? There were minimal changes from the previous version besides the Windows native library update. Can you clone the repo and execute mvn test?

Sorry for not providing sufficient background on the issue. Here are the details:

OS Version: Windows 11 , 64 bit Build 26100 (10.0.26100.8875)

Java Version: Java HotSpot(TM) 64-Bit Server VM (21.0.6+8-LTS-188)

Code snippet:

ITesseract tesseract = new Tesseract();
tesseract.setDatapath("tessdata");
tesseract.getWords(ImageIO.read(new File("reg_seg1.png")), ITessAPI.TessPageIteratorLevel.RIL_WORD);

mvn test also failed with multiple invalid memory access errors. test log

Make sure you have Microsoft Visual C++ v14 Redistributable installed. The installer can be found under Other Tools, Frameworks, and Redistributables section on Microsoft Download page.

Can you determine which commit started causing the Invalid memory access error?

I have Microsoft Visual C++ v14 Redistributable installed.

After running mvn test on the commits between 5.19.0 and 5.20.0, I can determine that the latest working commit is 84f45f6. The invalid memory access error appears since f5ccf68.
